모재구성판에 표면코팅층이나, 층간코팅층을 설치하여, 금속접촉에 의한 액체누설을 방지하도록 한 구조의 금속적층형 가스킷은 구체예를 기재할 것까지도 없는 공지이다.BACKGROUND ART A metal laminated gasket having a structure in which a surface coating layer or an interlayer coating layer is provided on a base material composition plate to prevent liquid leakage due to metal contact is known even without describing specific examples.

표면코팅층은, 기관의 가스킷 중합면에 부착되는 것에 의해, 중합면의 마이크로단위의 요철을 통과하는 유체(가스)의 누출을 방지하고, 또, 층간코팅층은, 가스킷모재 사이의 극간을 통한 유체(가스)의 누출을 방지하는 것이지만, 그 모재에 따라서 역 혹은 조임하중에 의해 함몰(압축영구변형)이 크고, 유체누설이 발생하는 문제가 있었다.The surface coating layer adheres to the gasket polymerization surface of the engine, thereby preventing leakage of the fluid (gas) passing through the unevenness of the microunits of the polymerization surface, and the interlayer coating layer is a fluid through the gap between the gasket base materials ( Gas) is prevented, but there is a problem that the depression (compression permanent deformation) is large due to reverse or tightening load depending on the base metal, and fluid leakage occurs.

본 발명은, 상기한 종래예의 문제점에 착안하여, 열이나 조임하중에 대처한 코팅층을 구비한 금속적층형 가스킷을 제공한다.SUMMARY OF THE INVENTION The present invention focuses on the above-described problems of the prior art, and provides a metal laminated gasket having a coating layer that copes with heat or tightening load.

복수매의 모재구성판을 적층하여 구성한 금속적층형 가스킷에 있어서, 모재구성판에 불소고무, NBR 등 기관의 가스킷 중합면에 대하여 융화성이 양호한 고무계의 소재에 의해 이루어진 표면코팅층과 실리콘수지, 불소수지, 에폭시수지 등 수지계의 소재에 의해 이루어진 층간코팅층을 설치하여, 이들 코팅층 사이에 상기한 모재구성판을 개재시킴과 동시에, 모재구성판의 적절한 곳에 액체구멍 밀봉용 비드를 설치한 구성을 기본으로 한다.In a metal laminated gasket formed by laminating a plurality of base material component plates, a surface coating layer made of a rubber-based material having good compatibility with a gasket polymerization surface of an engine such as fluorine rubber and NBR, a silicone resin, and a fluorine resin And an interlayer coating layer made of a resin-based material such as epoxy resin, interposing the above-mentioned base material component plate between these coating layers, and installing beads for sealing liquid holes in an appropriate place of the base material component plate. .

도면은 본 발명에 관한 금속적층형 가스킷의 실시예를 표시하는 것으로, 제1도는 제1실시예의 단면도, 제2도는 제2실시예의 단면도이다.The figure shows an embodiment of a metal laminated gasket according to the present invention, in which FIG. 1 is a sectional view of the first embodiment, and FIG. 2 is a sectional view of the second embodiment.

제1도에 표시하는 제1실시예는, 모재구성판인 상판(1), 하판(2) 및 중판(3)의 3매 구조로 이루어지는 금속적층형을 표시하고, 상판(1)과 하판(2)의 표면측에 불소고무에 의해 이루어지는 표면코팅층(4)을 층설하며, 중판(3)의 양면에 실리콘수지에 의해 이루어지는 층간코팅층(5),(5)을 설치하고, 이들 코팅층(4),(5) 사이에 상판(1), 하판(2) 및 중판(3)의 모재구성판을 개재하도록 하고, 중판(3)에는 액체 구멍(7) 밀봉용 비드(8)를 설치하는 구성이다.The first embodiment shown in FIG. 1 shows a metal laminated structure having a three-layer structure of a top plate 1, a bottom plate 2, and a middle plate 3, which are the base material composition plates, and the top plate 1 and the bottom plate 2 Surface coating layer (4) made of fluorine rubber is laid on the surface side of the sheet), and interlayer coating layers (5) and (5) made of silicone resin are provided on both surfaces of the intermediate plate (3). The base plate constituting plates of the upper plate 1, the lower plate 2, and the middle plate 3 are interposed between the five plates, and the bead 8 for sealing the liquid hole 7 is provided in the middle plate 3.

표면코팅층(4)은, 불소고무 외에 NBR 등 기관의 가스킷 중합면에 대하여 융화성이 양호한 고무계의 소재로 구성하고, 또, 층간코팅칭(5)은 실리콘수지 외에 불소수지, 에폭시수지 등으로 구성하여, 미끄럼성이 양호한 것을 사용하면 윤활에 의해 비드 꼭대기부의 코팅층의 박리(剝離)가 방지될 수 있어야 좋다.The surface coating layer 4 is made of a rubber-based material having good compatibility with the gasket polymerization surface of an engine such as NBR in addition to fluorine rubber, and the interlayer coating 5 is made of fluorine resin, epoxy resin, etc. in addition to silicone resin. Therefore, if a slipperiness | lubricacy is used, it should be able to prevent peeling of the coating layer of a bead top part by lubrication.

또, 표면코팅층(4)은 층간코팅층(5)의 층두께보다 두껍고, 층간코팅층(5)을 중판(3)에 층설시키지 않고, 상판(1) 및 하판(2)에 층설하도록 하여도 좋다.In addition, the surface coating layer 4 may be thicker than the layer thickness of the interlayer coating layer 5, and may be laminated on the upper plate 1 and the lower plate 2 without laying the interlayer coating layer 5 on the middle plate 3.

제2도에 표시하는 제2실시예는, 상판(1)과 하판(2)만으로 구성한 금속적층형 가스킷을 표시하는 것으로, 제1실시예와 마찬가지로 상판(1)과 하판(2)의 각각의 표면코팅층(4)을 설치하고, 층간코팅층(5)은 하판(2)측에 설치하며, 또 하판(2)에 비드(6)를 형성한 것으로, 잔여의 점은 제1실시예와 동일하다.The second embodiment shown in FIG. 2 shows a metal laminated gasket composed only of the upper plate 1 and the lower plate 2, and the surfaces of the upper plate 1 and the lower plate 2 are the same as those of the first embodiment. The coating layer 4 is provided, the interlayer coating layer 5 is provided on the lower plate 2 side, and the beads 6 are formed on the lower plate 2, and the remaining points are the same as in the first embodiment.

본 발명은, 상기한 구성으로, 열 및 조임하중에 의해 함몰이 크지만, 융화성(밀접성)이 우수한 고무계 소재에 의해 표면코팅층을 설치하고, 이것을 기관의 가스킷 중합면에 밀접시키도록, 또, 그다지 융화성을 필요로 하지 않는 층간코팅층을 함몰이 적은 수지계 소재로 구성하는 것으로, 가스킷 전체의 함몰을 저감하고, 내구성이 높은 밀봉성능을 구비한 금속적층형 가스킷을 제공할 수 있다.The present invention provides a surface coating layer made of a rubber-based material which is large in depression due to heat and tightening load but excellent in compatibility (adhesion), and closes the surface to the gasket polymerization surface of the engine. The interlayer coating layer, which does not require compatibility, is composed of a resin-based material with few depressions, thereby reducing the depression of the entire gasket and providing a metal laminated gasket having high durability and sealing performance.

또, 청구항 2의 발명에 의하면, 층간코팅층의 두께를, 최대한 얇게하는 것에 의해, 더욱 가스킷 전체의 함몰을 저감하는 것이 가능하다.In addition, according to the invention of claim 2, it is possible to further reduce the depression of the entire gasket by making the thickness of the interlayer coating layer as thin as possible.

또한, 청구항 3의 발명에 의하면, 비드가 변형할 때, 상, 하판은 표면코팅층에 의하여 기관에 고정되고, 중판만큼이 미끄러지는 것없이 변형이 원활하게 실시되며, 따라서, 설계한 바와 같은 밀봉면압(비드에 의해)을 얻게 된다. 또, 미끄럼에 의해, 비드 꼭대기부의 코팅층의 박리가 방지되고, 내구성이 높은 가스킷을 얻게 된다.In addition, according to the invention of claim 3, when the bead deforms, the upper and lower plates are fixed to the engine by the surface coating layer, and the deformation is smoothly performed without slipping as much as the middle plate, and accordingly, the sealing surface pressure as designed (By the bead). In addition, the sliding prevents peeling of the coating layer from the top of the bead, thereby obtaining a highly durable gasket.
